Embodiments of the present disclosure provide a communication system. The communication system may be a communication system using cellular mobile communication technology. FIG. 1 is a schematic structural diagram of a communication system in an embodiment of the present disclosure. As shown in FIG. 1 , the communication system 10 may include: a terminal device 11 and a network device 12 .

In an embodiment, the above-mentioned terminal device 11 may be a device that provides voice or data connectivity to users. In some embodiments, the terminal equipment may also be called user equipment (UE), mobile station (mobile station), subscriber unit (subsriber unit), station (station) or terminal (terminal equipment, TE), etc. The terminal device can be a cellular phone, a personal digital assistant (PDA), a wireless modem, a handheld device, a laptop computer, a cordless phone, Wireless local loop (WLL) station or tablet computer (pad), etc. With the development of wireless communication technology, devices that can access the communication system, communicate with the network side of the communication system, or communicate with other devices through the communication system are all terminal devices in the embodiments of the present disclosure. For example, terminals and cars in smart transportation, household equipment in smart homes, power meter reading instruments, voltage monitoring instruments, environmental monitoring instruments in smart grids, video monitoring instruments in intelligent complete networks, cash registers, etc. In the embodiment of the present disclosure, a terminal device can communicate with a network device, and multiple terminal devices can also communicate with each other. Terminal equipment can be static and fixed or mobile.

The above-mentioned network device 12 may be a device on the access network side used to support terminal access to the communication system. For example, it can be an evolved base station (evolved NodeB, eNB) in the 4G access technology communication system, a next generation base station (next generation nodeB, gNB), or a transmission reception point (TRP) in the 5G access technology communication system. ), relay node (relay node), access point (access point, AP), etc.

In the full-duplex enhancement project of the 3rd generation partnership project (3GPP), since transmitting and receiving are implemented simultaneously on one carrier, the transmitter and receiver need to be able to better suppress cross-slot interference and self-interference. Cross-slot interference can be measured, avoided and eliminated through certain mechanisms. For self-interference, the equipment needs to have high transmit-receive isolation to achieve strong self-interference suppression capabilities. Generally speaking, full duplex can bring benefits such as increased throughput, reduced transmission delay (especially uplink transmission), and enhanced uplink coverage. However, in order to minimize the impact on the complexity and radio frequency of terminal equipment, only network equipment supports full duplex, while terminal equipment still only supports half duplex.

For example, the full-duplex mode of a network device can include the following three situations:

The first is non-overlapping subband, that is, uplink information and downlink information are transmitted on different subbands, and there is no overlap between them in the frequency domain;

The second type is partial overlapping subband, that is, uplink information and downlink information are transmitted on different self-bands, and there is partial overlap between subbands in the frequency domain;

The third type is shared spectrum full duplex, that is, uplink information and downlink information can be transmitted on completely overlapping frequency domain resources.

It can be seen that when the network equipment supports full-duplex, the uplink subband (UL subband) used to transmit uplink information and the downlink subband (DL subband) used to transmit downlink information can be flexibly configured. So, in view of this situation, how the terminal device correctly receives the control signaling is an urgent problem to be solved.

In the embodiment of the present disclosure, the configuration of a control area (such as a control resource set (CORESET)) used to transmit control signaling is configured from the network device to the terminal device through high-level signaling. Among them, the following information can be included: CORESET ID, CORESET frequency domain configuration information, and other related information.

For example, the above-mentioned high-level signaling may include: radio resource control (RRC) signaling, broadcast messages, system messages, media access control (medium access control, MAC) control element (control element, CE), DCI Or the signaling carried by PDSCH, etc.

In order to solve the above problems, embodiments of the present disclosure provide a communication method, which can be applied to the terminal device described in one or more of the above embodiments, such as a UE.

It should be noted that in the embodiment of the present disclosure, CORESET is an example of a control area, and the above communication method is explained using this example. In the following embodiments, both the first control resource set and the second control resource set can be understood as CORESET.

Figure 2 is a schematic flowchart of a communication method on the terminal device side in an embodiment of the present disclosure. Referring to Figure 2, the method may include:

S201: The terminal device determines, according to the instruction of the network device, that the first frequency domain resource used to transmit part or all of the CORESET (ie, the first control resource set) is located in the uplink subband.

It should be understood that the network device indicates the frequency domain location of the uplink subband and the frequency domain location of the first frequency domain resource to the terminal device through high-layer signaling. Based on the frequency domain location of the uplink subband and the frequency domain location of the first frequency domain resource, the terminal device may determine that the frequency domain resource (ie, the first frequency domain resource) used to transmit part or all of the CORESET is located in the uplink subband. At this time, the first frequency domain resource is unavailable and cannot be used to transmit part or all of the CORESET.

In some possible implementations, a CORESET may include one or more resource blocks (RBs) in the frequency domain. The first frequency domain resource can be used to transmit a CORESET. The first frequency domain resources carrying different CORESETs may be located in different subbands.

S202: The terminal device does not monitor some or all of the control signaling on CORESET on the first frequency domain resource.

Here, the control signaling on CORESET refers to the control signaling in the search space (SS) associated with CORESET.

It should be understood that the uplink subband is used to transmit uplink information and cannot transmit CORESET. Then, after determining that the first frequency domain resource is located in the uplink subband through S201, the terminal device determines that the first frequency domain resource is unavailable. At this time, S202 is executed to not monitor part or all of the CORESET on the first frequency domain resource. Control signaling in associated SS.

In practical applications, one CORESET can be associated with multiple SSs, and one SS is associated with one CORESET.

Exemplarily, Figure 3 is a schematic diagram of a transmission resource in an embodiment of the present application. Referring to Figure 3, CORESET1, CORESET2 and CORESET3 are respectively transmitted in different first frequency domain resources. Among them, part of the frequency domain resources carrying CORESET1 (ie, the frequency domain resources on slot 3) are located in the uplink subband. At this time, the terminal device does not monitor the SS associated with CORESET1 on the frequency domain resources.

At this point, when the network device supports full duplex, after the terminal device determines that the frequency domain resource used to transmit part or all of CORESET is within the uplink subband, it confirms that the control area is not on the frequency domain resource, and does not execute the The frequency domain resources monitor the control signaling in the SS associated with part or all of the CORESET. In this way, the frequency domain location of the control area can be accurately determined, thereby ensuring the reliability of control information reception.

In some possible implementations, still referring to FIG. 2 , after S202, the above method may further include: S203 to S204.

S203: The terminal device determines the second frequency domain resource in the downlink subband according to the instruction of the network device.

It should be understood that the network device can also indicate the frequency domain location of the downlink subband to the terminal device. Then, after determining that the first frequency domain resource is unavailable through the above S201, the terminal device can determine the second frequency domain resource on other frequency domain resources in the downlink subband according to the instructions of the network device or the provisions of the communication protocol. Here, the second frequency domain resource can be used to transmit part or all of the CORESET.

In an embodiment, the terminal device may determine the second frequency domain resource according to the provisions of the communication protocol. For example, the communication protocol may stipulate that one or more frequency domain resources other than the first frequency domain resource may be used to transmit part or all of the CORESET. Then, the terminal device may use the one or more frequency domain resources as the third frequency domain resource. Second frequency domain resources. Alternatively, a resource offset (such as RB_offset) may be specified in the communication protocol, and the terminal device may offset the RB_offset based on the center frequency point of the first frequency domain resource to determine the second frequency domain resource.

In another embodiment, the terminal device may determine the second frequency domain resource according to instructions from the network device. Exemplarily, the terminal device receives the first indication information sent by the network device. The first indication information is used to indicate the frequency domain location of the second frequency domain resource. Then, the terminal device determines the second frequency domain resource according to the first indication information. In practical applications, the first indication information may include: the frequency domain position of the second frequency domain resource (such as the center frequency point of the second frequency domain resource), the resource offset of the second frequency domain resource relative to the first frequency domain resource Quantity (such as RB_offset), etc.

Of course, the terminal device may use other methods to determine the second frequency domain resource, and this is not specifically limited in the embodiments of the present disclosure.

S204: The terminal device monitors some or all of the control signaling associated with CORESET on the second frequency domain resource.

It should be understood that after determining the second frequency domain resource, the terminal device can monitor the control signaling in the SS associated with part or all of the CORESET on the second frequency domain resource.

Exemplarily, FIG. 4 is a schematic diagram of another transmission resource in an embodiment of the present application. As shown in FIG. 4 , CORESET1, CORESET2, and CORESET3 are respectively transmitted in different frequency domain resources. Among them, part of the frequency domain resources of CORESET1 (ie, the frequency domain resources in slot 3) are located in the uplink subband. At this time, the terminal device does not monitor the SS associated with CORESET1 on the frequency domain resources. And according to the RB_offset indicated by the network device, another frequency domain resource is determined on other downlink subbands (can be called a mirror frequency domain resource, such as other downlink subbands on time slot 3), and on the mirror frequency domain resource Monitor the associated control signaling on CORESET.

It should be noted that in the embodiment of the present disclosure, the execution order of S202 and S203 is not limited, and they can be executed one after another or at the same time.

In the embodiment of the present disclosure, when the network device supports full duplex, after determining that the frequency domain resources used to transmit part or all of CORESET are within the uplink subband, the terminal device determines other frequency domain resources as the control area. , and monitor the control signaling in the SS associated with part or all of the CORESET on the frequency domain resource. In this way, the frequency domain position of the control area can be accurately determined, thereby ensuring the reliability of control information reception.

Based on the same inventive concept, in an embodiment of the present disclosure, a communication method is also provided, which method can be applied to the terminal device in the above communication system. In this communication system, the terminal device can communicate with the network device supporting full duplex.

Figure 5 is a schematic flowchart of another communication method on the terminal device side in an embodiment of the present disclosure. Referring to Figure 5, the method may include:

S501: The terminal device determines, according to instructions from the network device, that the fourth frequency domain resource (equivalent to the above-mentioned first frequency domain resource) used to transmit part or all of the CORESET (ie, the second control resource set) is located in the uplink subband.

S502: The terminal device determines the third frequency domain resource (equivalent to the above-mentioned second frequency domain resource) in the downlink subband according to the instruction of the network device.

S503: The terminal device monitors some or all of the control signaling associated with CORESET on the third frequency domain resource.

It should be noted that the specific implementation process of S501 to S503 can refer to the specific description of S201, S203 to S204 in the embodiment of FIG. 2, and will not be described again here.

In an embodiment, S502 may determine the third frequency domain resource according to the provisions of the communication protocol. For example, the communication protocol may stipulate that one or more frequency domain resources except the fourth frequency domain resource may be used to transmit part or all of the CORESET. Then, the terminal device may determine this one or more frequency domain resources. It is the third frequency domain resource. Alternatively, a resource offset (such as RB_offset) may be specified in the communication protocol, and the terminal device may offset the RB_offset based on the center frequency point of the fourth frequency domain resource to determine the third frequency domain resource.

In another embodiment, S502 may also determine third frequency domain resources according to instructions from the network device. Exemplarily, the terminal device receives the second indication information sent by the network device. The second indication information is used to indicate the frequency domain location of the third frequency domain resource.
